2020-07-26Switch to integralimg 0.3.0 and use the new functions for integral sauvolaNick White
2020-07-23Update to v0.2.1 of integralimg, and improve various thingsNick White
- Improve integral sauvola by rounding threshold correctly - The Sauvola functions can now process any image.Image, not just an image.Gray - Add ImageWindower interface and use it to generalise wipesides.go - Rely on Bounds() for image bounds rather than implementation- specific stuff in integralimg Note that a couple of the wipesides tests are now failing. It's possible that this is due to fixed or introduced bugs (let's hope the former) changing sensible thresholds. Will need to look into this and sort it.
